VAPOBIZING APPARATUS.

Specification of Letters Patent.

Patented Jan.12,1915.

Application filed January 14, 1 14. Serial No. 312,132.

concern WALDECK, a citizen of the United States, residing at Baltimore, in land, have invented new and useful Imrovements in Vaporizing which the following is a specification.

The invention relates to a vaporizing apparatus, and more especially to improvements in the construction of vaporizing apparatuses forming the subject-matter of Letters Patent No. 1,068,288, issued to me and bearing date of July 22, 1913.

The primary object of the invention is the provision of an apparatus wherein the imrovements thereof render it more efficient, reliable in its working, and aid materially in reducing the cost of manufacture of the of the invention is the provision of an apparatus of this character which is designed for making breathable gas or vapor in the use of certain chemicals, medicaments to be administered for the treatment of nasal or other affections by inhalation, the apparatus being further adapted for the production of gas to be stored in a tank to be subsequently consumed therefor or used for running automobiles, or the like, or for the heating of boilers and similar devices.

A further object of the invention is the provision of an apparatus of this character wherein the chemicals when heated thereby will be prevented from burning and will be mixed with air so that the vapor or gas prosame.

Another ob ect duced will be discharged for fumigating or' purifying inclosures such as moving picture houses, theaters, or the like.

Other objects will be in part obvious and in part hereinafter pointed out.

The invention accordingly consists in the construction, combination and arrangement of elements as will be hereinafter described, illustrated in the accompanying drawings, and pointed out in the claims hereunto appended.

In' the drawings :-Figure 1 is an enlarged fragmentary vertical longitudinal sectional view through an apparatus constructed in accordance with the invention. Fig. 2 is asectional view on the line 2-2 of Fig. 1. Fig. 3 is a sectional view on the line 3-3 of Fig. 1. Fig. 4 is a fragmentary vertical longitudinal sectional view through the State of Mary- Apparatus, of

more fully a modified form of mixing cylinder or drum. Fig. 5 is a fragmentary verticallongitudinal sectional view through an apparatus showing a modification.

Similar reference characters indicate cor responding parts throughout the several views in the drawings.

-Referring to the drawings in detail, the

apparatus comprises a mixlng cylinder or drum 10 which is suitably mounted for rotation in any desirable form of support, and is formed at one end with a tubiform nipple 11 which serves as one of the journals therefor and is rotatably fitted within a sleeve 12 which is stationarily mounted in the support for the cylinder. This sleeve 12 is formed with externally threaded ends 13, on the outermost one of which is engaged a removable cap 14 having arranged therein-a packing disk 15, while surrounding the nipple or nozzle 11 and detachably connected with the inner threaded end of the sleeve 12 is a collar 16, the same carrying a washer 17 of any ordinary form, which, together with the disk 15, serve to render the sleeve 12 fluidtight so as to prevent the escape of fluid therefrom, the nipple or nozzle 11 being in direct communication with the cylinder 10 so as to admit the chemicals and air thereto whereby the same can be heated for producing gas for the various uses hereinbefore set forth.

ed in one side of the sleeve 12 is a feed plpe 18 through which is admitted the chemicals, the sleeve being formed with a boss 19 in which the end of the tube 18 is engaged, and this boss is formed withan inlet'passage 20 which is adapted to register with a port 21 provided in the nipple or nozzle 11, so that on the rotation of the cylinder 10 the nipple or nozzle 11 will simultaneously rotate therewith. The chemicals will be admitted to the said nipple or nozzle 11 on the registering of the port 21 with the passage 20 and will be automatically cutoff at intervals when the port 21 is moved out of registration with the passage 20 so that the chemicals will be admitted to the cylinder 10 at predetermined intervals during the working of the apparatus.

Arranged contiguous the sleeve 12 is a compressed air storage tank or reservoir 22 which has a connection 23 with the sleeve 12 for communication therewith, the nipple or nozzle.11 being formed with a port 24:

' through which is adapted to register with the passage througi the connection 23 to admit.

compressed air from the tank 22 into the nipple or nozzle 11, which air forces the chemicals into the cylinder for mixture therewith, the compressed air tank 22 bein supplied with compressed air through the tube 25 from any suitable source of supply. It will be noted that during the rotation of the cylinder 10 the chemical supply and also the compressed air supply to the same will be automatically controlled by the rotation of the nipple or nozzle 11 in the sleeve 12 so that charges of the same will be admitted at intervals when the apparatus is in action.

In Fig. 4 there is shown a modified form of cylinder, which comprises an outer cylindrical wall 26 and an inner cylindrical wall 27 which are spaced from each other to form a chamber 28 therebetween so that on the application of heat to the cylinder the chemicals admitted thereto will be prevented from burning, one end of the cylinder being provided with a removable head or cap 29, so that chemical compounds can be placed within the chamber 28, the discharge end of the cylinder being constructed in a manner similar to the construction set forth in Letters Patent N 0. 1,068,288, issued to me July 22, 1913.

In Fig. 5 there is shown a modified form of apparatus, wherein the cylinder 30 has its hollow journal 31 passed through a suitable cap 32 preferabl constructed as shown, and is formed with a circular head 33 which is rotatably mounted within a stationary sleeve 34 which carries the cap 32, the head 33 being designed to. work against a fibrous ring or washer 35, which, together with the head, forms a packing gland so as to prevent leakage at this point. Extended through the end of the sleeve 34 opposite the cap 32 is an air inlet nozzle 36 which receives a charge of air supplied from any suitable source. Formed on the sleeve 34 is a hollow boss 37 in which is fitted a delivery nipple 38 supporting a sight tube 39 connected with a reservoir or feed cup 40 fitted with the usual needle valve controlled discharge nozzle 41 which projects into the sight tube 39 and in alinement with the nipple 38, so that the chemicals held within the reservoir or cup 40 will be fed therefrom the nipple 38 into the sleeve 34 and the supply being regulated through the needle valve controlled nozzle 41 as usual.

The chemicals when admitted into the sleeve 34 will be acted upon by the compressed air discharged from the nozzle 36 so as to be driven into the cylinder 30 where the mixture will be vaporized for the subsequent discharge thereof from the apparatus, for use in the treatment of pulmonary troubles.

The head 33 is formed with an inwardly tapered entrance opening 42, which is dis posed in axial alinement with the nozzle 36 to assure the free admission of the chemicals and air through the hollow journal 31 into the cylinder 30, to be vaporized therein.

The apparatus is further adapted for the production of gas to be stored in a tank to be subsequently consumed for illuminating gases, breathable gases, and other purposes.

his apparatus when used without a storage tank is adaptable for automobiles, gas engines, gasolene engines, or the like, or for heating boilers and similar devices, and if. a tank be beneficial it may in some convenient way be attached to the apparatus for holding or storing the different kinds of gases.

To prevent the chemicals from burning on entering the heated cylinder the extra compartment or inner wall is provided, as shown in Fig. 4, so that the compounds will be held in the cylinder in a manner for the production of gases whereby on the introduction of the chemicals they will be prevented from burning, as such chemicals will not come in contact immediately on the entrance to the cylinder with the heated wall thereof as they will pass slowly over and through the compound used and thus be vaporized without burning.

It is to be understood that changes, variations and modifications may be made in the construction as come properly within the appended claims, without departing from the spirit of the invention or sacrificing any of the advantages thereof.
